WASHINGTON, Nov 16 (Reuters) - Billionaire Elon Musk, an adviser to U.S. President-elect Donald Trump, said on Saturday that Cantor Fitzgerald CEO Howard Lutnick would "actually enact change" if chosen as U.S. Treasury secretary.

Trump has not announced his nominee for the role, but Lutnick and investor Scott Bessent are serious contenders for the job and sources familiar with his thinking say Trump has been wrestling with picking one of the two or considering another option.

Musk said Bessent is "a business-as-usual choice."

"Business-as-usual is driving America bankrupt, so we need change one way or another," Musk said on X. "Would be interesting to hear more people weigh in on this for Trump to consider feedback."

Musk has been increasingly influential in Trump's inner circle and has been staying at the president-elect's Mar-a-Lago club in Palm Beach, Florida, as Trump forms his incoming government.

At a gala event on Thursday night, Trump teased Musk about his ongoing post-election stay at Mar-a-Lago.

"I can't get him out of here. He just loves this place. And I like having him here," said Trump.

At the end of the event, Musk mounted the stage.

"The public has given us a mandate that could not be more clear. The people have spoken, the people want change," he said.

Lutnick has been helping Trump with his transition efforts. He has praised the president-elect's economic policies, including his use of tariffs.
